hi every one, im new over here
I just spend a few days - weeks yet - to learn how works ELK solution. Seems a revolucionary concept - for my at all. (i was probing "splunk", "graylog" and similar solutions long time ago).
Kibana LOG trouble: License information from the X-Pack plugin could not be obtained from Elasticsearch for the [data] cluster.
Recently i has changed the elasticsearch architecture - to cluster (two nodes) ... then start all my particular hell. The ELK solution has working fine few weeks.... similar trouble. i tried to retur to singular elasticsearch server - but dont works any more - the index with troubles of sincronicity (delete all of them and i recreate it again) ... license troubles... retur to old snatch shot of elasticsearch ... same troubles and kibana too.
I use debian distribution to probe this kind of lab - finaly on separated machins to study the escalabillity too and another arquitecture aspets. All of them VMs.
Logstash 6.5.4
Elasticsearch 6.5.4
Kibana 6.6.0 (updated today)
Kibana is showing a license trouble.
Feb 12 12:02:03 Kibana kibana[371]: {"type":"log","@timestamp":"2019-02-12T11:02:03Z","tags":["license","warning","xpack"],"pid":371,"message":"License information from the X-Pack plugin could not be obtained from Elasticsearch for the [data] cluster. Error: Request Timeout after 30000ms"}
My configuration now - with the trouble (to try to solve it - but its the same)
Logstash.yml
...
xpack.monitoring.enabled: false
...
elasticsearch.yml
....
xpack.ml.enabled: false
xpack.monitoring.enabled: false
xpack.security.enabled: false
xpack.watcher.enabled: false
....
kibana.yml
...
xpack.graph.enabled: false
xpack.ml.enabled: false
xpack.monitoring.enabled: false
xpack.reporting.enabled: false
xpack.security.enabled: false
....
Any of them don't let my uninstall the x-pack module by the ELK elected for the probe.
